Popcaan performed in London for the first time yesterday, During MixPak’s set, which features the likes of Popcaan, Kranium, and many more, Popcaan screamed out “F*ck Wiz Khalifa” at the fellow artist and member of the crowd before debuting a new version of Drake’s hit single “One Dance.”

Wiz responded to the insult with some jabs of his own, calling Popcaan “Poptart” and claiming that he gave Drake a handjob.

Origins of this new rap beef seem unclear, but maybe people were just cranky because of a weed shortage at 02 Arena.i
